Sizing
Which plan fits your Project Zomboid server?
Our estimate of the memory a Project Zomboid server uses, and the smallest plan that covers it. Heavy modpacks can need double.
Memory climbs with players and with how much of the map they explore. Lite suits a handful of friends on vanilla, Plus is the sweet spot for modded servers up to 30–40 players, and Max is for heavily modded roleplay servers.
| Players | Vanilla | Lightly modded |
|---|---|---|
| 8 | ≈ 4.2 GB · Plus | ≈ 6.3 GB · Plus |
| 16 | ≈ 5.4 GB · Plus | ≈ 8.1 GB · Pro |
| 32 | ≈ 7.8 GB · Plus | ≈ 11.7 GB · Pro |
| 64 | ≈ 12.6 GB · Max | ≈ 18.9 GB · VDS |
